Modern elemental analysis using a modern wavelength-dispersive X-ray spectrometer ensures a non-destructive and environmentally safe analytical method. All elements of the periodic table from beryllium to uranium can be determined using qualitative, semi-quantitative and quantitative measurements in solids, powders and liquids. Depending on the specific application, concentrations from the ppm level up to 100% can be analyzed. Advantages of XRF analysis include easy and fast sample preparation, multi-element capability, high precision and reproducibility, and very short measuring times. For normal routine XRF analysis of trace and major elements in mining samples (rocks, minerals, metals, slurries, etc.), sample preparation is quite simple and rapid, and consists of crushing, then grinding (to well below 0.05 mm) and finally pressing the powdered material into pellets. Depending on the analytical demand, fused beads are preferable for the analysis, but solid samples like metals can be directly analyzed after polishing the measuring surface. For analyzing liquid samples, liquid cups or filter preparations can be used. The analytical XRF software, combined with the flexible sample changer concept, optimizes all process and laboratory automation projects, and is open for easy integration with customized software packages and computer networks without influencing the reliability of the standard software product.
